Vitamin D deficiency and supplementation in pregnancy in a multiethnic populationbased cohort Åse R. Eggemoen1*, Ragnhild S. Falk2, Kirsten V. Knutsen1, Per Lagerløv1, Line Sletner3, Kåre I. Birkeland4,5 and Anne K. Jenum1
Abstract Background: To investigate ethnic differences in vitamin D levels during pregnancy, assess risk factors for vitamin D deficiency and explore the effect of vitamin D supplementation in women with deficiency in early pregnancy. Methods: This is a population-based, multiethnic cohort study of pregnant women attending Child Health Clinics for antenatal care in Oslo, Norway. Serum-25-hydroxyvitamin D [25(OH)D] was measured in 748 pregnant women (59 % ethnic minorities) at gestational weeks (GW) 15 (SD:3.6) and 28 (1.4). Women with 25(OH)D
